Definitions
- This invention relates to a microbiological culture device of a type which comprises an elongate plate carrying a culture, medium, a tubular case for said plate, and a stopper made fast with one end of said plate and closing said case.
- Such inspections are carried out, e.g. by health officers, with the aid of microbiological culture devices by bringing a small plate or slide which carries the culture medium into lapping engagement with the kitchen work surfaces, such as tables, shelves of various description, and so forth, for the purpose of picking up any bacteria therefrom.
- prior devices only enable lapping of the work surfaces limited to the edge regions thereof. Where the central region of a surface is to be lapped, then the plate must be taken apart from the stopper and manipulated in this detached condition, with the risk of coming into contact with the culture medium.
- a device as indicated being characterized in that it comprises a hinge formed on said plate at the end thereof made fast with the stopper.
- said hinge is an elastically deformable bridge formed integrally with the plate.
- FIG. 1 is a sectional view taken through a device according to the invention along the line I--I of FIG. 2;
- FIG. 2 is a sectional view through the device shown in FIG. 1, taken along the line II--II;
- FIG. 3 is a sectional detail view of the device of FIG. 1 at a different stage of its operation.
- FIG. 4 is a perspective detail view of the device shown in FIG. 1.
- the numeral 1 designates generally a microbiological culture device according to the invention.
- the device 1 comprises a small elongated plate, or slide, 2 of substantially rectangular shape, having two opposed ends 3 and 4, and two opposed faces 5 and 6.
- Zones are defined on the faces 5 and 6, one on the face 5 and two on the face 6, which are formed with suitable corrugations to accommodate respective culture media T1, T2, and T3.
- the device 1 further comprises a tubular case 7 having a skirt 8, bottom 9, and opening 10.
- the plate 2 fits inside the case 7 in a guided sliding fashion, with the end 3 next to the bottom 9 and the end 4 substantially level with the opening 10.
- Indicated at 11 is a stopper which is a press-fit over the skirt 8 to close the case opening 10, and is fast with the end 4 of the plate, thereby providing a handgrip for the plate.
- the stopper 11 has an impression 16 sized to accommodate a bottom 9 of another device identical with the device 1 in a predetermined snug fit relationship so as to provide a stack of the devices.
- a hinge Formed on the device 1 of this invention, at the end 4 of the plate, is a hinge, indicated at 19, around which the plate is swung in an angularly displaceable manner.
- the hinge 19 is embodied by a small bridge 20 formed integrally with the plate, which is made deformable elastically by its slender thickness dimension.
- the projections 21 and 22, and projections 23 and 24, are sized to come into mutual abutment relationship when the plate completes a predetermined angular movement around the hinge, thereby acting as stops for said angular movement.
- the maximum angle allowed for the angular movement is about 45° in either directions.
- the stopper 11 is located sufficiently away from the plane defined by the face 6 or the plane defined by the face 5 of the plate.
- the stopper can be easily grasped (see FIG. 4) for lapping over a surface P to be tested in any areas of the surface by means of the plate.
- the lapping can be effected with a desired pressure of the plate 2 on the surface P to be tested. It will be sufficient, in fact, to exert an appropriate pressure on the stopper-grip for transfer to the plate via the projections 21 and 22, or 23 and 24, in mutual abutment relationship.
- the main advantage of the device according to this invention is that it enables lapping over a surface at any locations thereof.
- a further advantage of the invention device is that the surface lapping operation can be carried out easily at a desired pressure of the plate on the surface being tested.
- the device of this invention is simple construction-wise and inexpensive to manufacture, which are not neglibible advantages in the instance of an article which must be produced on a large volume basis and discarded after use.
